Question

当我启用Doctrine过滤器时，我和Twig以及WebProfiler有一个奇怪的错误。

request.CRITICAL: Uncaught PHP Exception Twig_Error_Runtime: "An exception has been thrown 
during the rendering of a template ("Error when rendering "http://community.localhost:8000/
_profiler/e94abf?community_subdomain=community&panel=request" (Status code is 404).")." at 
/../vendor/symfony/symfony/src/Symfony/Bundle/WebProfilerBundle/Resources/views/Profiler/
layout.html.twig line 103

此{{ render(path('_profiler_search_bar', request.query.all)) }}会导致错误。

我的学说过滤器允许在某些类上添加过滤器约束（带有动态子域的多租户应用程序）

<?php

namespace AppBundle\Group\Community;

use Doctrine\ORM\Mapping\ClassMetadata;
use Doctrine\ORM\Query\Filter\SQLFilter;

/**
 * Class CommunityAwareFilter
 */
class CommunityAwareFilter extends SQLFilter
{
    /**
     * Gets the SQL query part to add to a query.
     *
     * @param ClassMetadata $targetEntity
     * @param string        $targetTableAlias
     *
     * @return string The constraint SQL if there is available, empty string otherwise.
     */
    public function addFilterConstraint(ClassMetadata $targetEntity, $targetTableAlias)
    {
        if (!$targetEntity->reflClass->implementsInterface(CommunityAwareInterface::class)) {
            return '';
        }

        return sprintf('%s.community_id = %s', $targetTableAlias, $this->getParameter('communityId')); // <-- error
        // return ''; <-- no error
    }
}

我还扩展了Symfony Router，以便在路由中自动添加子域占位符。

你知道是什么原因引起的吗？

更新

namespace AppBundle\Routing;

use AppBundle\Group\Community\CommunityResolver;

    public function __construct(BaseRouter $router, RequestStack $request, CommunityResolver $communityResolver)
    {
        $this->router = $router;

     */
    public function match($pathinfo)
    {
        return $this->router->match($pathinfo);
    }

    public function generate($name, $parameters = array(), $referenceType = UrlGeneratorInterface::ABSOLUTE_PATH)
    {
        if (null !== ($community = $this->communityResolver->getCommunity())) {
            $parameters['community_subdomain'] = $community->getSubDomain();
        }

        return $this->router->generate($name, $parameters, $referenceType);
    }
}

我找到了解决方案，事实上我通过了我的＆＃34;租户＆＃34; （这里是我的＆＃34;社区＆＃34;）会话就像这样（在订阅者onKernelRequest中）

if (null === ($session = $request->getSession())) {
    $session = new Session();
    $session->start();
    $request->setSession($session);
}
$session->set('community', $community);

我更改为将此对象存储在服务中并且它可以正常工作。使用Session存储数据可能是一种不好的做法。

我认为您的Symmfony路由器覆盖可能会导致问题。你能把代码粘贴给我们吗？
